tte it known that l, Ensosnicx Int'omea citizen of the lnited States,residing nt Allegheny, in he manly of Allegheny and tate ot'Pennsylvania, have invented certain new and useful Improve-atenta in'liles or lattels nml .llethodaof Mamtfact tiring tln Same; and l doherebydeclare the following to be a fall, cleanand exacty liewriplion ofthe invention, reference heilig.' had to the accompanying drawings,which form part nf this specilcnlion.

My invention' relates to decorative tiles or poneis and to methods nfmanufacturing tho mole, and has for its ohjectthe production ot' a eastiron or steel tile or pam-i adapted and designed for use as n substitutefor the ordinary'and welldanown terracotta orothcr vitreous tiles andponeis now extensively used in the decorative art..

In carrying my invention into edcct I lirst produce a cast ironersteelhase or body having any desired pattern in relief on one or more of itssurfaces, as hy casting.r iron in a suitable mold, and then, havingtilted the mtnglioor depressed portion of the pattern-snr face withasnitableenamelingmaterial of any desired color or of various colors ntwill, I linke the article nntil the enamel has lia-mty adhered to themetal. and tinally finish the projecting portions of themetallie surfaceby :zrindlngnml polishing, electroplating, nr nthr erwise.

In practice I havefoumi itdesirnble to cont the entire surface of thearticle with an enamel of light color, which' is baked in preri finelyto applying the adored ennmels to the intaglio portions of the surface,und which is remotcd from the raised portion niv the pnttern .ly thegrinding.' operation lioforr rcferred tu.

My invention vomisls in, lirsl, as a amv article of manufacture, t rastiron or steel tile or panel havilmamiaod metallic pattern 'indinterstitial depressed enana-led spacvmnod, secondly, iatheprocessolprotlncinglhc snnn. hereinafter dost-ritmi nml claimed.

ln tlaaci-oinlmnyng drawings, Figaro l is a plan vicw,and l'ic. :l asectional view, ol' a lilo constructed according 'o my invention, illethickness nl' lllootattlm-lt'll sarlat-asl ring greatly exaggerated soasto la cas-ily distln cnishnble.

A designates the hase or body ol' tio tile, which is preferably nmallealilwiron casting, and which is formed with the raised surfaces a an, which constitute the pattern in relief, Upon the pattern-surface A isplaced first n coating Il of vitreous enamel of aaycolor. generally oflight hun, which is then well baked. This first coating islaid all overthe surface and may bemind ceneraily is,applied tn tlm back and edges aswell asthe patternsnrface, the article being dipped in n hath ofenana-ling material. Attctho coating llhnx dried to the proprrdegreelhearticle is baked in a suitable fornace until the enamel fuses andodin-rcs to tho metal. 'lheartiele is then cooled and a second coating'of enamel is applied, hat only to theintagiioor depressed portions In hl of the pattern lhe enamel isappliedjn a liquid form and allowed todr\,when theartirlc is again talked, as befcire,and again allowed to cool.In imi.'- ing the enamel spreads itself smoothly over tlm surface of themetal and liccutnes bright and lossy, the sarlat-e living similar tothat ot' well-halted ille of llneqnality. 'llenthc mantel fases on thesurface of the tile, it creeps up the edttesol the raised parts of thopattern to the lop of the samcand covers the sides of the fillets thatcompose the pattern and add greatly to the artistic elteet.

After the enameled coatings imre been appletLas described, the raisedpnrtsof the pa|- tern are ground, removing tlteenamcl therefrom, arepolished. and finally electroplated or otherwise matt-ll with gold,silver, nickel, or other metal.

'lllc bright metallic surfactof the raised portions ot llnpatterncontrasting,r with tin` raamt-lcd intaglio portions produce a highlyartistic and iwantii'nl eil'oct not attainable in tiling.: of theordinary character.

The coanwliog of llal pattern may lnitt a single color or in a varietyol colonat will nml according to llnpurpose lor which thv lilo is to In`asciiandthetnstoot' thv operator.
